SPECIFICATION forming part of Letters Patent no. 752,513, dated February 16, 190;.

Application filed April 16, 1902.5

To all whom it may concern/ sLoWEN, a citizenof the Empire of 1 Ger i many, residing in New'York, borough of the Bronx, and State of New Yorln'have invented I certain new'and useful Improvements in Machines for Bending the Cross-Heads and Eyes 5 of Wire Bale-Ties, of which the following is a a specification. 3

This invention relates to certain improvements in machinesfor bending the cross-heads 3 and eyes of wire bale-ties; and the object of; this invention is to produce the bending of the f cross-head or eye by foot-power and then impart a rotary motion tothe bending devices on their axes for a predetermined number. of times for twisting the shank of the cross-head or eye without transferring the bale-tie to a separate twisting mechanism and for this purpose the invention consists, primarily, of.

or eye and then automatically twisting the shank of the same by imparting rotary motion on their axes to the bending devices in conholding the wire blank and the end of the cross- 5 head or eye, the bending operation being performed by foot-power, whilethe twisting of i the shank of the cross-head or eye isperformed V The invention consists, further, of the combination of the bending devices for the ends I of the wire bale-tie with clamping devices for holding the body of the wire and the shank of f the cross-header eye firmly in position and of twisting devices operated from the driving-i shaftfor imparting immediately on the'comtwisting motion to the shank of the same', as will befull'y described hereinafter and finally j pointed out in the claims.

Similar letters of reference indicate corresponding parts. i

Referring to the drawings, A represents the table of my improved machine for bending the cross-heads and eyes of wire bale-ties.

The table is supported on suitable standards,

1 at the lower part of which the operating-treadle (not shown) is arranged.

H represents an elbow-lever which isfulcrumed to legs on the table A, the upper arm ,of the lever extending through a slot in the tableAand being provided with aforked end having a'ntifriction-rollersh, which engage a sliding sleevec, thatis s'plined to'the main r shaft B. The main shaft B is supported in journal-bearings of upright standards F G, which are attached to the upper part ofthe table A. The lower arm of the elbow-lever ject lugs c at right angles to the ears 0, to

which are pivoted rods R R which serve for the purpose of operating the cranks R R, that are located, respectively, at opposite sides of the wire-bending mechanism. The main shaft B is provided at its end with a flattened head, as shown in Fig. 3, to which the bending mechanism for the cross-head or eye is attached.

The cross-head-bending mechanism consists of a plate P, which is secured to one side of the flat head and provided with a raised rim 12 that is recessed at its upper part for in serting the wire blank 2. The parts for bending the end of the wire blank 2 are arranged on the inner surface of the plate Pwithin the rim p of the same; In a bore of the plate P is arranged a pivot; T, which passesthrough the plate and the flattened head of the shaft B. On the end of the pivot T is mounted a bending-arm t which carries at its outer end a pin t, by which the end of the wire blank 2 is bent over toward the body of the same. In the center of the pivot T is arranged a stationary pin t, which serves to hold the wire blank during the bending operation in forming the cross-head or eye. A second pin 6 is arranged on the bending-arm t eccentrically to the center pin If, so as to hold the wire during the bending operation without pressing the wire blank tightly against the center pin. Below the pivot T of the bending-arm t is arranged in the plate P a second pivot T, on which pivot is mounted the die V for bending the hook of the cross-head, said hook-bending die being provided with a' recess and twonoses '0 0, one at each side of the recess. Sidewise of the pivot T is arranged on the plate P a pin U, which serves for supporting the wire blank 2 when the same is inserted in the upper recessed part of the rim p of the plate P and into a recess in the end of the main shaft B, as'shown in Fig. 6. The bending-arm t is operated by means of gear-wheels S S of which the gearwheel S is secured on the rear end of the pivot T, while .the gear-wheel S is mounted on a pivot S which is journaled in bearings of the plate P and located in the same horizontalplanewith the pivot T. The forward motion of the sliding sleeve C operates by the rod R the crank R and thereby the actuating-gears S S of the bending-arm 25 while the rod R operates by the crank R the hook: bending die V. The (center pin t and pins t 25 located on the bending-arm 25 as well as the pin U on the inner face of the plate P,

project slightly beyond the rim 0 0f the plate P, as shown clearly in Fig. 8. plate P is loosely mounted upon the pivots T and S and shifted laterally toward the plate P during the bending operation imparted to the end of the wire blank, so that the ends of the pins t, t, 25 and U project into a suitable recess in the plate P and retain the wire blank against lateral displacement before the twisting operation commences. The laterally-shifting movement of the counter-plate P is eifected by two cam-surfaces 0 p of-which the cam 0 is arranged on the counter-plate P concentrically with the pivot T, while the cam 0 is tightly secured to the pivot T. As soon as the action of the cam surfaces 0 p is interrupted the counter-plate P is returned from the position shown in Fig. 9 into the position shown in Fig. 8 by means of two helical springs p which are placed on pins 0 of the counter-plate P, said pins being kept in position by means of sockets 10, located in projections at diametrically opposite points of the plate P, as shown clearly in Figs. 6 and 10.

Adjacent to the cross-head-bending devices and transversely thereto is arranged an upright bracket N, which is attached to the table A by means of suitable bolts, as shown in Figs. 1, 2,3, and 11. this bracket N is attached a laterally-projecting arm n,'to which a clamping-block N is pivotally connected. The clamping-block N is connected by a rod N, which is guidedin a suitable opening of the table A and extended to some distance below the table. In the adjacent edges of the bracket N and the clamp-d ing-block N are arranged small recesses a n,

which engage the body 'of'the wire blank 2 and the bent-over end 'of the cross-headrespectively, so as to hold them firmly in posi' To the upper end of A counterthe shank of the cross-head firmly'in position of the recesses n 12 the rod N is applied a transverse pin niwhich To the lower'end of is actuated at the proper time by the free arm of a lever M, which is fulcrumed to the lugs The opposite end M and the movable clamping-jaw N-'are operated at the proper time by the elbow-lever bending operation.

H and the connecting-rod foot-treadle.- I

. The devices for bending the end of -thewire blank 2 in the shape of an eye are shown in Figs. 18 to 16. These bending devicesare.

constructed similar to the devices for bending the cross-head, with the difference that the hook-bending die V is dispensed with. The supporting-plate P is attached to the flattened head of the, main shaft Him the same manner as the plate P of the cross-head. The arm t carries at its outer end the pin i for bending the end-of the wire blank, while the centerpin 2, is arranged in the pivot T, so as to serve as a support for the wire during the bending operation, which is assisted by the pin 25', arranged eccentrically on the pivot T, so as to hold the wire blank e-in position during the A pin a is secured'upon the inner face of the plate P for limiting the length of the eye. A recess in the 'bending. armf passes over the pin a when the end of the wire .2 has been bent into shape of the I eye, as shown in Fig. 14. For operatingthe bending-arm t a vgear-wheel S is keyed to the pivot T and meshes with a gear-wheel S,

that is secured to the pivot S which is supported by the plate P. On both sides of the pivot S cranks R R are located, which are connected with the sliding sleeve G by means of shiftingrodsRR respectively. A counterplate P is loosely mounted upon the pivot S and kept in position of rest away from the plate P by means of helical springs, while it is pressed againsttheplate P by the-movement of the sleeveC through the medium of the camsurfaces pf 39 which turn upon each other, the came-surface p beingin tight connection with the pivot S The pins t andt project beyond the rim of the plate P-and enter a suitable recessof the plate P when pressed against the plate. P, so as to-secure thereby the wire .2 inpositionfor the twisting operation.

The cross-head or eye bending devices are operated by the depression of the treadlezby the ,foot of the attendant. bending operation is accomplished the shanks of thecross-head or eye are firmly clamped by the jaws N N and held in. position ready for the twisting operation. e

The twisting operationof the shank is accomplished by the following mechanism: On the main shaft B is mounted a loose pulley E, which may be thrown into operative connection with the mainshaft B by a clutch device 6. Immediately after. the cross-head or eye is'bent'by the bending mechanism-the pulley is clutched to the shaft B by means of asliding sleeve D, which is loosely mountedon the mainshaft B. The sliding sleeve D is operated by a lever K, which projects, throughan opening. in the table A to some distance below the same. The upper forked end. of the lever K engages the flanges at the ends of the sliding sleeve D by means of rollers'K. A

H,operated' by the As soon as the helical" spring K connects the lower end of the lever K with the stationary arm on the under side of the table,'so as to draw thelower end of the lever'K toward the right, as shown in Fig. 1, and press a pin K on the same against the face of a disk f whichismouhted at the end of a shaft f, that is supported in brackets F G, which are attached to the under side of the tableA. The diskf is provided with a recess, which is engaged by the pin K of the lever K. To the rear end of the auxiliary shaft f is applied a sprocket-wheel B which receives rotary motion byasprocketchain from a sprocket-wheel B on the main shaft B in the ratio of three to one. The power transmitting mechanism described is put in operation by depressing the treadle, and thereby oscillating the elbow-lever H.- The lower arm of the fulcrumed lever H is pivotally connected with aslottedlink -L,the slot of which is guided on a fixed pin projecting from a bracket (0 at the under side of' the table A. The opposite or lower end of the slotted link L is pivotally connected with a rod L whichmay be called'a ratchet-bar. This ratchet-bar L engages a pin on the lower end of the lever-K, the pin it having a flattened upper face which serves as a support for the ratchet-bar L when the machine is in a position of rest. The ratchet-bar L has on its under side a recess, one side Z of which is nearer to its pivot and is inclined toward the free end of the bar, while the opposite side runs approximately at right angles to this bar, so as to form one side of a tooth Z the outer side of which is also inclined -toward the end "Z of the ratchet-bar L The ratchet-bar L is prevented from shifting lat erally by a- U-shaped keeper is, attached to the lower end of the lever K. When in moving the ratchet-bar L the flattened pin it enters the recess of the angle bar U, the tooth Z engages the pin is and moves thelever Kinto the position shown in dotted lines in Fig. 1, so that the pin K 'is withdrawn from its socket in the disk f, while its upper end'engages' the clutch device 6 and imparts rotary motion to the shaft Bfor producing the motion of the shank of 'the cross-head. vAn angle-arm f which projectsdownwardly from the supporting bracket-arm F, serves as a support for the free endZ during the forward movement of the bar L Fig. 17 shows the arrangement of a machine for producing simultaneously the cross-1 head at the end of one wire. blank .2 and the eye'at the end of a second wire blank .2 by means of cross-head and eye bending devices, respectively, on two separate shafts B blank 2 during the twisting operation, while -a single clutch device is used for setting both .B the shaft B carrying the eye-bending mechanism at its flattened head and having Y adjacent thereto'ase'parate pair of clamping j jaws for tightly holding the end of the wire shafts B and B and sprocket-chains be-' tween said sprocket-wheels and between the shaft B and the auxiliary shaft f.

My improved machine for bending the cross-heads and eyes of wire bale-ties is operated as follows: After inserting the wire blank 2, as shown in Figs. 1, 2, and 6, into position between the open clamping-jaws N N and the bending devices the treadle is depressed, so that the elbow-lever H is placed by the connecting-rod H in position shown in dotted lines in Fig. 1. By the oscillation of the elbow-lever H the sliding sleeve C is shifted on the main shaft B by the upper forked end of the elbow-lever H, so as to operate by the intermediate motion-transmitting mechanisms the bending-arm t and the hook-forming die V and bend thereby the end of the wire blank into the shape of the cross-head, as shown in Fig. 7. The bending of the end of the wire blank around the pin t, which is solely effected by the action of the pin 25 upon the outer end of the bending-arm t leaves sufficient play between the wire and the pin 6 for easily removing the finished cross-head, as'pin 2f, being eccentrically arranged to the center pin in the pivot T, does not press the wire against the center pin 2?, but serves as an auxiliary support for the wire blank during the bending operation. A short time after the bendlng-arm t has commenced its operation the hook-forming die commences to turn; but it does not act on the wire blank until the bending motion performed by the bending-arm is nearly completed, so as so prevent thereby any shifting and unusual strain on the wire blank when the hook-forming die commences its work. The object ofpreventing unnecessary tension in the cross-head is furthermore insured by the form of die- V, the nose 0) of which enters first into operation. At the same time that the die V begins to turn the counter-plate P is shifted laterally on the pivots T and S by means of the cam-surfaces 19 p mounted, respectively, on pivot T and the plate P itself, as shown in Fig. 9. In this position the plates P P thoroughly secure the Wire blank and later on the finished crosshead, so as to prevent any lateral movement during the clamping and twisting operations.

The springs 12 being compressed by the lateral shifting of the plate P, effect the-return of the latter into its normal position after the clamping surfaces are released from each other. The clamping jaws, by which the shanks of the cross-head are securely held in bringing the clamping-jaw N toward the clamping-j aw N, and secure thereby the shank of the cross-head firmly in position, as shown in Fig. 11. As soon as thecross-head is finished and engaged by the clamping-jaws the clutch device a is thrown into engagement for transmitting rotary motion to the shaft B for producing the twisting of the shank of the cross-head. During the depression of the,

- treadle the slotted link L, which is pivoted to the lower end of the arm of the elbow-lever H, is moved upwardly into the position shown in dotted lines in Fig. 1, thereby sliding and turning upon the pivot Z, secured to the bracket a.

At the beginning of this movement the ratchetbar L slips upon the pin 76 and effects the movement of the lever K only at the moment when the tooth Z reaches and pulls the pin k, thus causing the pin K to leave the recess in the disk f. During the operation of bending the cross-- head the lever K is turned upon its pivot, as there is some play between the lever K and the clutch device 6. 1 At the moment when the cross-head is finished and the clampingjaws hold the shank of the cross-head the pin K is released from its recess in the face of the disk f" and the clutch is thrown into engagement with the pulley E, thus rotating the main shaft B. By means of a sprocket-wheel transmission B B motion is transmitted in' the relation of three to one to the shaft f of the disk f As the ratchetbar L is supported at its outer end Z by the angular rod f in such a position as to allow the lever K to slip back, since the tooth Z is finally elevated above the flattened face of pin 70, the lever K will return into its position of rest as soon as the disk f has completed one full revolution, when pin. K will enter the recess in the disk f without regard to the release of the treadle. The ratio in the transmission of power limits the rotation of the main shaft B to three rotations, so as to impart to the shank of the cross-head three twists and finish thereby the eross-head, as shown in Fig. 12.

The operation of the wire-bending devices for the eyes of bale-ties is shown in Figs. 13 to 16 and is nearly the same as the operation described for bending the cross-heads,'only that the hook-forming die is removed. It requires, therefore, no further description. Either "thewire-cross-head-bending devices or the eye-bending devices may be attached to the flattened-head of the shaft B. The rods R R .operatingthe cranks R R on the ends of the pivotS and the intermediate gearwheels produce the operation of the wirebending arm 25 The latter completes its operation at the same time as the hook-forming device-that is to say, just before the rotation of the main shaftB begins. The counterplate P for securing the eye during the' bending operation is pressed against the plate P in the same manner as that described for the cross-head-bending operation by means of cam-surfaces p 19 The operation of the combined shafts B B for forming a cross-head and an eye on wire bale-ties a 2' requires no further explanation. By the double machine both a cross-head and an eye can be bent at the same time, one operation of the treadle, one clutch device, and one mechanism for limitingthe number of rotationsof the ends of the wire blanks onlybeing necessary for actuating both bending and twisting devices. r p a Having thus described my invention, Iclaim I as new and desire to secure by Letters Patent 1.
